Kim Kardashian West's second child due in December

Kim Kardashian West's second child is due in December.

The reality TV star - who already has a 23-month-old daughter North with her husband, rapper Kanye West - confirmed she had fallen pregnant once again earlier this week and is expecting to give birth in December, a source has told E! News.

It is also thought the blossoming family could have two more mouths to feed by Christmas after sources close to the star revealed she is expecting twins yesterday (02.06.15).

While the raven-haired beauty has been open about her struggle to conceive for the second time after undergoing IVF, it has since been reported she is having a double pregnancy following her attempt to have two eggs fertilised during the treatment.

A source said: "Kim has told a handful of people that she had in vitro and that two eggs were fertilised. She is waiting to see if they both 'stick' before she makes any kind of announcement.

"She has to wait and see if they are both OK. And she is waiting to get an OK from her doctor that both the fertilised eggs are healthy."

Kim has also confessed she's suffering from "really bad" morning sickness and has struggled to get out of bed since she fell pregnant.

She said: "To be honest, I've had really bad morning sickness, day sickness, night sickness - I can barley get out of bed."

Although she insisted feeling "s**t* is "so worth it" as the couple had worried they may never be able to add to their brood.
